Abstract

A 35-year-old man with mesenteric metastases of unknown primary was referred for 18F-FDG PET/MRI. The images demonstrated that FDG accumulated in the chest, abdomen, bilateral kidneys, and external genitalia. Renal and testicular metastases were suspected. The primary tumor was still not found. In addition, kidney biopsy findings indicated a diagnosis of IgA nephropathy.
